Interesting conversation.
I skimmed over the comments so if this was mentioned before, please forgive me.

I like the idea of an Instant power down, it could be a good way quickly exit if something bad is going on or, if you need the funds for something important in your life, I am also in favor of a power down tax.

I don't understand why Tax a Power up, or perhaps I don't understand the logic in that, we want people to power up HP, not cash it out, so, that should be free or may I suggest even rewarded.

Power down tax

I suggest, we tax it on the speed at which you want to power down.

Normal 13 week power down = 0% tax
7.5 week power down = 10% tax
3.25 week power down = 15% tax
1 week power down = 30% tax
instant power down = 40% tax

or something along those lines... then depending on the rush you are in to exit, you would pay a higher fee to exit that quick.

Just and idea. ;)
